Nail-Biting Detected

Habits like nail-biting run on autopilot: cue, behavior, relief, repeat — usually before you're even aware it's happening. RewireMe breaks that loop with a jolt of awareness at the exact right moment.
Your webcam notices the motion
On-device AI watches for the moment your hand goes to your mouth — processed locally, frame by frame, never recorded.
A randomized sound fires instantly
RewireMe plays one of several different alert tones at random, so your brain can never tune it out or predict it.
The sound snaps you into the moment
That split-second surprise is enough to pull you out of autopilot and back into conscious awareness.
You choose a different response
With awareness restored, you get to pick a competing habit instead — the small choice that, repeated, rewires the loop.
Built to run entirely on your machine
No account, no cloud, no camera roll of your worst habit floating around somewhere. RewireMe was designed from day one to keep everything local.

Your camera feed never leaves your computer
Most habit-tracking tools ask you to trust a server somewhere. RewireMe was built the opposite way: every frame is analyzed locally and immediately discarded. There's nothing to leak because there's nothing being sent.
No account required · No cloud sync · No footage saved
People are already noticing the difference
A few early reactions from people using RewireMe to catch the habit in the moment.
"I've always bitten my nails and nothing worked — until RewireMe started popping up on my screen. Now I actually have the chance to catch it and correct the habit right then and there."
"I used to feel so embarrassed at work chewing my nails during calls. Now I get a nudge from RewireMe, and it's helped me stay mindful."
"It's like having an accountability buddy on my laptop. I love that it's free and private — no footage leaves my computer."
Any questions?
Everything people usually ask before they download.
No. RewireMe runs completely offline — detection, alerts, and everything else happen locally on your computer. It never needs a connection to function.
No. Nothing is recorded, saved, or transmitted. Each frame is analyzed in the moment and discarded immediately — there's no file, no cloud copy, and no one else who can ever see it.
A fixed sound becomes background noise fast — your brain learns to filter it out within days. By varying the tone each time, RewireMe keeps the interruption effective for longer, so it keeps doing its job.
